Donald Trump on Monday suggested he had broadened the scope of his investigation regarding President Obama's background, arguing that - in addition to making inquiries into Mr. Obama's citizenship - he was "looking into" the president's college career.

In an interview with the Associated Press, Trump alleged that Mr. Obama had been "a terrible student," and wondered how he could have been accepted to prestigious schools like Columbia and Harvard Universities.

"I heard he was a terrible student, terrible," Trump told the AP. "How does a bad student go to Columbia and then to Harvard? I'm thinking about it, I'm certainly looking into it. Let him show his records."

Mr. Obama received an undergraduate degree in political science from Columbia University in 1983, after transferring from Occidental College in 1981. He went on to study law at Harvard Law School , where he was named the first black president of the Harvard Law Review. He graduated magna cum laude in 1991.

Trump provided no evidence of Mr. Obama's "terrible" marks, but did offer the fact that "I have friends who have smart sons with great marks, great boards, great everything and they can't get into Harvard."

"We don't know a thing about this guy," Trump said. "There are a lot of questions that are unanswered about our president."

"I heard" and "I have friends who" are the mist lightweight elements in an argument that you can use. What a jerk.
